| 摘要: |
| 为了研究胶州湾网采浮游植物的种类组成与数量变化, 作者根据2010年的胶州湾调查资料, 对调查区浮游植物丰度、优势种类和季节变化进行分析研究。结果表明, 胶州湾浮游植物主要由硅藻和甲藻两大类组成, 硅藻占据绝对优势地位。除了7月以外, 甲藻/硅藻比均<0.2。生态类型主要以近岸广布种和暖温带种为主, 在不同季节也出现了少数暖水种和外洋种。浮游植物丰度表现为明显的“双周期”, 冬、春两季较高, 夏、秋两季较低。 2月为全年最高峰, 数量为1108×104 个/m3, 10月为夏、秋两季的高峰, 数量为458.7×104个/m3。浮游植物群落的多样性指数平均为1.9。 |

| Abstract: |
| Based on survey data of phytoplankton in 2010 in the Jiaozhou Bay, the annual variations of the phytoplankton species composition and abundance distribution in 2010 were analyzed in this paper. Results show that the phytoplankton community in the Jiaozhou Bay mainly consisted of diatom and dinoflagellate. The dinoflagellate: diatom ratio in most months was less than 0.2, except in July. The ecological types were mainly neritic eurytopic species, temperate species, warm temperate species, and a few warm water species and oceanic species appeared in different seasons. There were two peaks of phytoplankton cell number in a year. The primary peak occured in February, when the phytoplankton cell number was 1108×104 cells/m3, and the second peak occured in October, when the phytoplankton cell number was 458.7×104 cells/m3. The average community diversity index was 1.9. |
